Omit Duplicate Only When In Sequential Order - sql

I've got a query returning the following information. I used Over(PARTITION BY to include row numbers. I'm capturing every time my work_center_S begins a new Order#, but I want to exclude the beginning of a new order when the part_number was the same as the order/row previous to it. I'm not able to use the DISTINCT function because a part_number may appear numerous times a day and I'll need to capture every time such a change occurs.

How I can I add a count to rank null values in SQL Hive?

This is what I have right now:
| time | car_id | order | in_order |
|-------|--------|-------|----------|
| 12:31 | 32 | null | 0 |
| 12:33 | 32 | null | 0 |
| 12:35 | 32 | null | 0 |
| 12:37 | 32 | 123 | 1 |
| 12:38 | 32 | 123 | 1 |
| 12:39 | 32 | 123 | 1 |
| 12:41 | 32 | 123 | 1 |
| 12:43 | 32 | 123 | 1 |
| 12:45 | 32 | null | 0 |
| 12:47 | 32 | null | 0 |
| 12:49 | 32 | 321 | 1 |
| 12:51 | 32 | 321 | 1 |
I'm trying to rank orders, including those who have null values, in this case by car_id.
This is the result I'm looking for:
| time | car_id | order | in_order | row |
|-------|--------|-------|----------|-----|
| 12:31 | 32 | null | 0 | 1 |
| 12:33 | 32 | null | 0 | 1 |
| 12:35 | 32 | null | 0 | 1 |
| 12:37 | 32 | 123 | 1 | 2 |
| 12:38 | 32 | 123 | 1 | 2 |
| 12:39 | 32 | 123 | 1 | 2 |
| 12:41 | 32 | 123 | 1 | 2 |
| 12:43 | 32 | 123 | 1 | 2 |
| 12:45 | 32 | null | 0 | 3 |
| 12:47 | 32 | null | 0 | 3 |
| 12:49 | 32 | 321 | 1 | 4 |
| 12:51 | 32 | 321 | 1 | 4 |
I just don't know how to manage a count for the null values.
Thanks!
You can count the number of non-NULL values before each row and then use dense_rank():
select t.*,
dense_rank() over (partition by car_id order by grp) as row
from (select t.*,
count(order) over (partition by car_id order by time) as grp
from t
) t;

SQL Server : sort ranking list

I have a table with 3 columns ordernum, username, and amount. I want to select its rows and show an additional column expected.
The rule for calculating the expected column is as follows:
These rows same OrderNum value will be ranking again based on amount column (Desc order). I don't know how I can describe, but the expected result is shown below :(
I tried with RANK() and ROW_NUMBER(), but have not been able to properly apply above algorithm.
This is my table declaration:
CREATE TABLE data
(
ordernum INT,
username NVARCHAR(30),
amount MONEY
);
This is my table content:
+----------+----------+------------+
| ORDERNUM | USERNAME | AMOUNT |
+----------+----------+------------+
| 1 | test01 | 18382.5079 |
| 1 | test02 | 10476.0000 |
| 1 | test03 | 8128.0000 |
| 1 | test04 | 6680.0000 |
| 1 | test05 | 5388.9673 |
| 1 | test06 | 5356.0000 |
| 12 | test07 | 2806.0000 |
| 12 | test08 | 2806.0000 |
| 12 | test09 | 2806.0000 |
| 14 | test10 | 2530.0000 |
| 15 | test11 | 2330.0000 |
| 16 | test12 | 2183.0000 |
| 16 | test13 | 2182.0000 |
| 17 | test14 | 2000.0000 |
| 18 | test15 | 1621.0000 |
+----------+----------+------------+
And this is my expected result:
+----------+----------+------------+----------+
| ORDERNUM | USERNAME | AMOUNT | EXPECTED |
+----------+----------+------------+----------+
| 1 | test01 | 18382.5079 | 1 |
| 1 | test02 | 10476.0000 | 2 |
| 1 | test03 | 8128.0000 | 3 |
| 1 | test04 | 6680.0000 | 4 |
| 1 | test05 | 5388.9673 | 5 |
| 1 | test06 | 5356.0000 | 6 |
| 12 | test07 | 2806.0000 | 12 |
| 12 | test08 | 2806.0000 | 12 |
| 12 | test09 | 2806.0000 | 12 |
| 14 | test10 | 2530.0000 | 15 |
| 15 | test11 | 2330.0000 | 16 |

How do I do this, please?
You seem to just want aggregation by user_id:
SELECT s.user_id, COUNT(distinct t.trip_id) as trips
FROM trips t INNER JOIN
session s
ON s.session_id = ANY(t.session_ids)
GROUP BY s.user_id ;
I'm pretty sure that the COUNT(DISTINCT) is unnecessary, so I would advise removing it:
SELECT s.user_id, COUNT(*) as trips
FROM trips t INNER JOIN
session s
ON s.session_id = ANY(t.session_ids)
GROUP BY s.user_id ;

Each account has multiple locations and each location has multiple RSCs.
I need to get last three RSCs for each location for AccountA.
I have tried the below query:
SELECT tblAccountwiseLocation.LocId,tblAccountwiseLocation.AccId,tblRSCMaster.RSCNo,tblRSCMaster.DateOfAddition FROM tblAccountwiseLocation
INNER JOIN tblRSCMaster ON tblAccountwiseLocation.LocId= tblRSCMaster.LocId
where tblRSCMaster.AccId=1
But not getting the proper output.
Please help me out.
Thank you all in advance.
You can wrap the existing query inside a common table expression, and use ROW_NUMBER() to get only the last 3 (by tblRSCMaster.DateOfAddition) entries per tblAccountwiseLocation.LocId.
WITH cte AS (
SELECT tblAccountwiseLocation.LocId,
tblAccountwiseLocation.AccId,
tblRSCMaster.RSCNo,
tblRSCMaster.DateOfAddition,
ROW_NUMBER() OVER (PARTITION BY tblAccountwiseLocation.LocId
ORDER BY tblRSCMaster.DateOfAddition DESC) rn
FROM tblAccountwiseLocation
INNER JOIN tblRSCMaster
ON tblAccountwiseLocation.LocId = tblRSCMaster.LocId
AND tblAccountwiseLocation.AccId = tblRSCMaster.AccId
WHERE tblRSCMaster.AccId=1
)
SELECT LocId, AccId, RSCNo, DateOfAddition
FROM cte
WHERE rn <= 3
ORDER BY LocId, AccId, DateOfAddition
An SQLfiddle to test with.
Is this what you need?
select m.*
from (select m.*, row_number() over (partition by accID
order by DateOfAddition desc) as seqnum
from tblRSCMaster
where m.locid = 1
) m
where seqnum <= 3
order by AccId, DateOfAddition;
I think you need to filter on the locid rather than on the AccId to get what you want.
